5 issues were found when checking AAR metadata:


  1.  Dependency 'androidx.navigation:navigation-common:2.7.0-beta02' requires libraries and applications that
      depend on it to compile against version 34 or later of the
      Android APIs.

      :app is currently compiled against android-33.

      Also, the maximum recommended compile SDK version for Android Gradle
      plugin 8.0.1 is 33.

      Recommended action: Update this project's version of the Android Gradle
      plugin to one that supports 34, then update this project to use
      compileSdk of at least 34.

      Note that updating a library or application's compileSdk (which
      allows newer APIs to be used) can be done separately from updating
      targetSdk (which opts the app in to new runtime behavior) and
      minSdk (which determines which devices the app can be installed

長いですが要するに、


androidx.navigation:navigation-compose:2.7.0-beta02

が依存している以下、


androidx.navigation:navigation-common:2.7.0-beta02
androidx.navigation:navigation-runtime:2.7.0-beta02
androidx.navigation:navigation-common-ktx:2.7.0-beta02
androidx.navigation:navigation-runtime-ktx:2.7.0-beta02

は、


Android API 34

以上を必要としているので使えません。

ということのよう。

 

💉 なぜ私は、Android API 33 だったけか

「Flamingo」なのでそれが最新安定版。

androidx.navigation:navigation-compose が 2.7.0-beta02 で NG だが 2.7.0-beta01 で OK な件

Android Studio Flamingo | 2022.2.1 を使ってる場合、33 までです。

Kotlin Serialization を使って JsonObject を作る方法

一番簡単に作る方法はどれなのか、と思いましたので。

サードパーティーは使わず、

すべて kotlinx.serialization で。

以下の JsonObject を作ります。


{
  "model": "gpt-3.5-turbo",
  "messages": [
    {
      "role": "user",
      "content": "Server-Sent Events とは"
    }
  ],
  "temperature": 0.7,
  "stream": false
}

 

👨‍🎨 文字列から作る

文字列内に JSON を記述しておいて変換します。


val str = """{
  |  "model": "gpt-3.5-turbo",
  |  "messages": [{"role":"user","content":"Server-Sent Events とは"}],
  |  "temperature": 0.7,
  |  "stream": false
  |}""".trimMargin()
val element = Json.parseToJsonElement(str)

println(element)
println(element.javaClass.simpleName)

// {"model":"gpt-3.5-turbo","messages":[{"role":"user","content":"Server-Sent Events とは"}],"temperature":0.7,"stream":false}
// JsonObject

 

👨‍🎨 データクラスから作る

データクラスを先に作っておきます。


@Serializable
data class ChatRequest(
  val model: String,
  val messages: List<Message>,
  val temperature: Double,
  val stream: Boolean
)

@Serializable
data class Message(
  val role: String,
  val content: String
)

値をセットして変換します。


val data = ChatRequest(
  model = "gpt-3.5-turbo",
  messages = listOf(Message(role = "user", content = "Server-Sent Events とは")),
  temperature = 0.7,
  stream = false
)
val element = Json.encodeToJsonElement(data)

println(element)
println(element.javaClass.simpleName)

// {"model":"gpt-3.5-turbo","messages":[{"role":"user","content":"Server-Sent Events とは"}],"temperature":0.7,"stream":false}
// JsonObject

 

👨‍🎨 Json エレメントビルダー で作る

ビルダー関数 buildJsonArray(), buildJsonObject() を使いながら DSL 形式で JSON の構造を定義していきます。


val element = buildJsonObject {
  put("model", "gpt-3.5-turbo")
  putJsonArray("messages") {
    addJsonObject {
      put("role", "user")
      put("content", "Server-Sent Events とは")
    }
  }
  put("temperature", 0.7)
  put("stream", false)
}

println(element)
println(element.javaClass.simpleName)

// {"model":"gpt-3.5-turbo","messages":[{"role":"user","content":"Server-Sent Events とは"}],"temperature":0.7,"stream":false}
// JsonObject

👨‍🎨 まとめ

文字列から作成する方法が直接的で簡単に書けますね！

【OpenAI】Kotlin OkHttp で Server-Sent Events (SSE)

ChatGPT API で stream 受信したいですよね。

stream　boolean　Optional　Defaults to false

If set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message.

👉 API Reference - OpenAI API hatena-bookmark

簡単にできそうなのでやってみました。

 

📡 curl

curl で簡単に取得できる。


curl "https://api.openai.com/v1/chat/completions" \
  -H "accept: text/event-stream" \
  -H "authorization: Bearer $OPENAI_API_KEY" \
  -H "content-type: application/json" \
  -d '{
    "model": "gpt-3.5-turbo",
    "messages": [{"role": "user", "content": "Server-Sent Events とは"}],
    "stream": true
  }'




...

data: {"id":"chatcmpl-7OQ1xuBFfam8Ct","object":"chat.completion.chunk","created":1686054286,"model":"gpt-3.5-turbo","choices":[{"delta":{"content":"て"},"index":0,"finish_reason":null}]}

data: {"id":"chatcmpl-7OQ1xuBFfam8Ct","object":"chat.completion.chunk","created":1686054286,"model":"gpt-3.5-turbo","choices":[{"delta":{"content":"います"},"index":0,"finish_reason":null}]}

data: {"id":"chatcmpl-7OQ1xuBFfam8Ct","object":"chat.completion.chunk","created":1686054286,"model":"gpt-3.5-turbo","choices":[{"delta":{"content":"。"},"index":0,"finish_reason":null}]}

data: {"id":"chatcmpl-7OQ1xuBFfam8Ct","object":"chat.completion.chunk","created":1686054286,"model":"gpt-3.5-turbo","choices":[{"delta":{},"index":0,"finish_reason":"stop"}]}

data: [DONE]

パースはだるそうですが、取得はできてるようです！

では、いざ、Kotlin で。

 

📡 okhttp-sse

壊れてるのか何なのか微妙。


testImplementation("com.squareup.okhttp3:okhttp-sse:4.11.0")

👉 okhttp/okhttp-sse at master · square/okhttp · GitHub hatena-bookmark

現在の安定版 4.11.0 ではあやしい。

5.0.0-alpha.11 ではまあまあ動いてるのでそれで。



SSEは、日本語で表現するとサーバ送信イベントと表現されるもので、サーバからクライアントに対してリアルタイムでイベントを送信することができる機能です。 コネクションを張っておいて、サーバからイベントを好きなタイミングで送れるイメージです

カンファレンスでの公演資料とか、時間が経つと、まあ動かないこと多いですよね！
